Hi Sid:
I added this to my function file:
function StoRSI(RSIPer,EMAPer)
{
Low1=LLV(C,7);
High1=HHV(C,7);
return (EMA(100*(C - Low1)/(High1 - Low1),EMAPer)/2) + (RSI(RSIPer)/2);
}
Note the naming and the variable positions in the declaration of the StoRSI function.
I plotted this in my IB window:
X=StoRSI(14,13);
Plot(50,"",7,1);
Plot(X,"StoRSI",5,1);
The C/O/H/L/V arrays are always available, so I only "passed" two variables, the EMA period and the RSI Period. It gets "passed" when you write the function within your regular AFL code. In my case, following what a lot of others do, I #include a regular (and growing) MyFunctions.AFL file.
Hope this helps.
Ken

Subject: [amibroker] passing variables
I use StochRSI fairly often and rather than re-write it all the time I
decided to make a dedicated AFL file that I can include in the other files
where I want to use the function. Of course to be of any use, the
variables need to be passed from the calling program to the included
program. I know how to do that in TS, but I don't see how to do it in AFL.
For my StochRSI fn I would want to pass the Array (usually Close), the RSI
period and the smoothing MA to the include file. Three variables in all.
How is this done?
TIA
Sid
